Thank you for the info BAKED. My bottle pressure is always at 1000 psi. I will pull 3 or 4 degrees out and lean it out. I have a 41 fuel jet I will try that one and see where it gets me. I will try and do this on wednesday of this week. I will post pics of the plugs and see what you guys think. If the 41 fuel jet is still to fat I will have to order some jets.

 

If the 41 is still fat you can always up the nitrous jet to an 80 or so... Just a thought.

 

Thats a good idea. I will let it rip on wednesday. I will be back to see what you guys think. I have about 6 new plugs left. I have to order a couple more boxes. What cylinders should a put them in? I want to say thanks to everyone that who has given me advise. I really appreciate it!

 

All new plugS if you can with that big of a change. Basically starting all over again.

 

I would pull minimum of 4* while leaning it out to run clean.

 

You are saying pull 4 more degrees from what I am running now correct? I am just pulling them from the high and low tables. Out of the whole table is that ok?

 

I'd go to a step colder plug as well as going down on the fuel. Or, as Baked suggested go up to a 80 nitrous jet and a 41 fuel, That would probably clean it up alot, pull another 3 degrees while you're at it and I'd get a #8 plug in the car.

 

I am running a number 8 plug B8efs

 

Here is a 41 fuel and 78 nitrous. Bottle full and at 1000 psi. Pulled 4 more degrees. What do think?

Looks pretty good, how did it run?

was that a 1/4 mile pass or 1/8th?

run the bottle at 950psi not 1000.

 

It felt good. better then the run before with the 45 and higher timing. It was ran hard all through 2nd and up to 5800 in 3rd. I was on my test strip not running on a track. Hope that is ok to do that?

 

OK then when you go to the track you need to take some more timing out.
Fuel looks real close.

Pull 2* more out and make some 1/8th mile hits, Should be close.
Might need 3 or 4* out to make it thru 1/4 mile.

 

Looks pretty good. I'd def pull a couple degrees and go from there. What was your total timing on the bottle and did my way of pilling timing work better for you?

 

Yes your way worked very well for pulling timing CAM. Thank you very much.
HP says I am running 14.5 for timing under WOT. So you guys say I need to pull 3 more for 1/4 mile? You have all been a great help thank you!

 

I'd pull 2 more. What are you running for fuel? To me that looks like you may be at about the limit of the fuel as well, might need a little more octane. Try taking the timing out first, start with 3, see what they look like, if that takes care of everything you're good... if not then maybe it's time for a little race fuel.

If you have all the O2's off and no cats ( I'm sure there's no cats in the car) the race fuel wont' hurt anything fwiw. Just messes the O2's and will KILL the cats fast... like one day.

Definitely looks better though. Is that the same heat range plug, or did you get a colder one in there?

 

Like said above... fueling looks good now. Pull 2 or 3 more and see where you are. I would do it at the track vice street so you have MPH data to compare and see what it wants...

 

Not only that the track will give you a full 1/4 mile pull to really see what it's doing, you may or may not be getting that on the street.

 

I am running my o2 sensors still. What kinda of race fuel would you recomend? I was thinking a should do a 50/50 mix. I am running pump gas now.I will pull 2 more out because my next track run will be a 1/4 track.

 

If you've been on strait pump, any type of leaded race fuel will work. But, you really need the O2's turned off first. Open loop tune would probably serve you well at this point anyway.

As for fuel, just get what's available, and be consistant about what you run. If you know there's say 3 gal's of fuel in the tank, put 3 gal's of whatever in there that you can consistantly get.

Best would be to just run it strait, obviously it's expensive and if you're driving the car to the track, it's gonna get alot more expensive.

Try it though, get to the track with 3 gal's in the car if you can, and then put 3 gal's of race fuel in, 112, 114, 116, whatever you can consistantly get. I like competition fuels, used to be torco. Stuff for me is available, and was always consistant/good. Nothing wrong with VP, Rockett, Sunoco, they are all good fuel.

Might be a good idea to think about a standalone fuel system at this point, so you can just run a 116 type fuel with the nitrous and pump the rest of the time. Not the cheapest way, but a good way to do it IMO.

Most of the racers will agree, this will give you teh ability to adjust fueling with pressure, in small incremets as well, giving you more tunability. A standalong with a fuel flow ga. would be my next reccomendations.

 

I have a local VP dealer. He said I can get 110 Unleaded fuel would that work? I can use that with my o2's right? I am not the best at tuning so I dont know how to tuning out the o2 sensors properly right now. Also we have no tuners around here. I now I should have a stand alone system that will be next on my list. My car gets put in a enclosed so I have no problem running it straight if I need to.
